This volume contains a selection of refereed papers from the 1993 Canadian Workshop on Information Theory, held in Rockland, Ontario, May 30 - June 2. The workshop provided a forum for Canadian and international researchers to gather and discuss new results in the areas of information theory, algebraic coding, digital communications, and networks. A number of novel approaches to research problems are presented, and seminal works by several renowned experts are included in the volume. The papers have been loosely grouped into four parts: coding and cryptography, coding and modulation of fading channels, decoding techniques, and networks and information theory.
